If you are are fortunate enough to have the liquidity needed (E.g.: you've already participated in a successful exit in a startup in your home country), there is always the EB-5 investor visa. (invest a half a million to a million dollars and create 10 jobs)

Obviously not an option for everyone, but if it is available to you, it may be one of the easiest ways, as you can get a green card relatively quickly via that route.
